Re3: Anon. array of refs to a range generated list of scalars.

Actually, the error message from print do( 'fred' ); confuses me completly.

What error message? You are aware of the different variants of do? From perldoc -f do

do BLOCK
  [...]

do SUBROUTINE(LIST)
  [...]

do EXPR
  Uses the value of EXPR as a filename and executes
  the contents of the file as a Perl script.

so probably the file named 'fred' doesn't exist and do returns simply undef - at least that's what it does here (on perl 5.6.0) generating thus a warning about Use of uninitialized value in print ...

Your right of course, I didn't think about the `do EXPR;` form at all. If I do `print do('fred')\|\| warn $!;` I get `No such file or directory at ...` Examine what is said, not who speaks. The 7th Rule of perl club is -- pearl clubs are easily damaged. Use a diamond club instead.	[reply] [d/l] [select]
